FreeFileSync fully supports long file paths with more than 260 characters, copies NTFS extended attributes, security permissions and alternate data streams. It can copy locked files using the Volume Shadow Copy Service, compare file content in binary mode, handle symbolic links and run real two-way synchronizations including detecting conflicts and propagating deletions. FAT).įreeFileSync includes features that are normally found only in the premium versions of commercial applications. This even works in mirror synchronization scenarios where the target file system does not support file IDs (e.g. This avoids time consuming file copy and delete operations and instead completes the task with a single hard drive access.

Batch jobs can be started with a simple mouse double-click or triggered automatically by a task scheduler.įreeFileSync detects moved files and reproduces the move on the target drive. Users can set up mirror, two-way, or custom synchronization rules, and then create batch jobs that run the sync without requiring manual interaction. This further enhances FreeFileSync's capabilities to not only work with local drives and network shares but also synchronize mobile and cloud storage.įreeFileSync eliminates the tedious and error-prone task of manually identifying files that have changed on the source folder and copying them to the target folder, no matter what protocol is used to access files. The new version supports synchronization via FTP (File Transfer Protocol) and the encrypted variant FTPS (SSL/TLS). A huge thanks to everyone who is contributing to make this possible!Ĭross-Platform File and Folder Synchronization Software adds Support for FTP and FTPSįreeFileSync ( ) has released version 9.1 of its free open source file synchronization utility for Windows, Linux, and macOS. Beginning with version 10, the project is fully relying on donations from users to finance its ongoing expenses in software development and support. Binary-comparison also processes all files in parallel.īefore version 10, FreeFileSync had shown a single advertisement during installation to help fund the project. Folder comparison will issue multiple requests at a time even when traversing only a single folder, by dynamically managing the workload while recursively reading the folder tree.

The new parallel file operations architecture is not limited to the synchronization step, but used throughout the application. The idle time after issuing each file I/O request while waiting for the network response is not the limiting factor anymore: The number of parallel operations can be set as high as needed until the bandwidth is saturated and the network card is operating at full speed. This new design offers huge performance improvements for all scenarios that are dominated by latency, like synchronization against network shares or cloud devices including SFTP and FTP(S). During synchronization FreeFileSync will then spawn several tasks accordingly instead of processing only one file after another. It is now possible to specify the number of parallel file operations for each device inside the settings. FreeFileSync version 10 has added support for copying
